[Cefuroxime axetil (Zinnat)--laboratory and clinical study].

The authors investigated the antibacterial action of cefuroxim in vitro and proved its relatively broad spectrum of action. Administration of the esterified form, Zinnat, produced very satisfactory therapeutic concentrations of cefuroxim in serum, bile tissue of operated gallbladders. The prophylactic administration of the combined parenteral and oral form of cefuroxim proved excellent in biliary surgery in twenty patients.

At relatively low MIC's it is active against staphylococci, streptococci, pneumococci, branhnamella and chlamydiae, higher concentrations are needed against enterococci and some strains of H. influenzae.

Long-term antibiotic susceptibility pattern of strains of Neisseria gonorrhoeae isolated in Czechoslovakia in the years 1957-1982.

Over the past 25 years a total of 7492 strains of Neisseria gonorrhoeae have been isolated in Czechoslovakia, mainly in Prague (64%). All these strains have been tested for susceptibility to the following antibiotics: penicillin G, ampicillin, tetracycline, spectinomycin, erythromycin, doxycycline, kanamycin, rifampin, chloramphenicol, gentamicin, cephalothin, cephaloridine, lincomycin and clindamycin. In addition, seven derivatives of newer antibiotics of penicillin and cephalosporin series were tested in 1981.
